To L7/Z whom it may concern.-

Be it known that I, SAMUEL CLARK NORTON.,

a citizen of theUnited States, and a resident of Hinckley, in the county of Fine, in the State of Minnesota, have invented certain new and useful Improvements in Oar Lock and Seal Combined, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying d rawiugs, in which- Figure l is a side view. Fig. 2 is a vertical sectional view of a portion of a freight-car provided with my lock and seal, and Fig. 3 is a horizontal sectional view of a portion of a freight-ear with my improved. lock attached thereto. Fig. 4L is an enlarged front view-oi' the same. Fig. is an enlarged longitudinal sectional view of the lock on the line x a? of Fig. l. Fig. 6 is an enlarged sectional view 2o of the lock on the line y 310i Fig. 5, and Fig.

7 is an enlarged cross-sectional view on the line e of Fig. 6. Fig. 8 is an enlarged detached perspective view of the door-holding bolt. Fig. 9 :is a similar view of the graduated wheel and the ratchet..r Figs. l() and 1l are perspective views showing the form of the bolt and hasp when soft-metal seals or similar fastenings are to be used. Fig. l2 is a perspective view, detached, of the locking-lever. Fig. 13 is a perspective view of the graduated drum.

This invention relates to the fastenings of the doors of freight-cars; and it consists in a bolt 'for holding the door closed, which is actuated by a spring or other means, and adapted, when it springs out to lock the door, to turn a graduated wheel or drum and expose to view a certain number or mark to denote the station where the door was last closed, as hereinafter shown.

The invention further consists in providing means for using soit-metal seals or other similar means for securing the door, as hereinafter shown.

In the drawings, A represents the frame or body oi' the car; B, the door, arranged to slide upon a wayf7 a, in the ordinary manner.

C is a metal frame or casing embedded in the side of the car, just in the rear ol the door B, when the latter is closed, and provided with a spring-bolt, D, adapt-ed, when pressed outward by the spring Z1, to hold the door closed, as shown in Figs. l, 2, and 8.

. E is a small lever, pivoted at c in the casing C, and having a right-angled end, d, held up into a socket, c, (see Fig. 8,) in the bolt by a spring, g, so that thev lever will lock the bolt D outward, as shown in Figs. 5 and 7.

F is a key adapted to be inserted through a key-holen, in the face of the casing @,to throw 6o the lever E downward and release the bolt D, so that it maybe pushed in to enable the door B to be opened.

Mounted upon the pivot ofthe bolt D, or at any other suitable point in the casing C, is a graduated drum or wheel, G, and ratchetwheel H, the graduations of the drum and the teeth of the ratchet corresponding in number.

17 is a small spring-pawl pivoted to the holt D, and engaging with the teeth of the ratchet 7C H, so that the movement of the bolt will be communicated to the ratchet and drum.

The graduations on the periphery of the drum will be numbered, lettered, or otherwise marked to enable them to be easily distinguished, and may be of any required number. In the drawings l have shown them numbered from l to 18 5. but any greater or lesser number may he used, if desired. The easing Chas a hole, m, cut through it opposite the 8o center of the drum G, and the throw of the bolt D and the length of the teeth on the ratchet H will so correspond that each stroke of the bolt will revolve the drum the distance of one of its graduations, hence each move- S5 ment of the bolt will expose a diiit'erent number to view through the hole n1.. rlhe lower face of the drum Gwill be provided with a series of holes, t, in a circle concentric with the outer rim of the drum, and corresponding 9o in number with the graduations and ratchet' teeth, into one of which a small pin, w, on the lever E :lits when in the position shown in Fig. 6, to hold the drum and prevent its being turned from the outside through the hole m. When the ordinary lead or other soft-metal seals or similar 'fastenings are to be used either in addition to or in place of the ratchet and drum G Il., I form the outer end of the bolt D with a slot, r, into which abolt or hasp, I, 10c attached to the door B, rits when the door is closed, and insert the lead seal or other fastening through holes t in the bolt and hasp. Vhen a car is loaded and the door closed, the bolt D Will spring out behind it and hold it closed, and at the same time the lever E will catch the bolt and prevent its being pushed in again unless the lever b e released by the key F. The springing out of the bolt Dvsets and fixes the position of the drum'G, so that Whatever letter, figure, or other mark is exposed to view through the hole m Will remain until thedoor is again opened, when the next niark will be exposed. When the dooris first closed, the person having charge of the billing of the cars records on the bill with the number or other distinctive mark ofthe car the number exposed through the hole m. Then, if the car contains through-freight, the agent at the end of the line can know, by comparing the bill with the .lock-number, Whether the car has been opened during its transit. If the car contains Way-freight, then .the agent opening the car Will record upon the bills the numbers exposed both before and after opening, so that the bills Will show at what stations the car was opened. By this simple means a perfeet check is secured upon the conductors and freight agents, and enables the railroad ofcials to locate all the points at which the cars .are opened.

Having described my invention and set forth its merits, what I claim is-.

l. The combination .of a sliding car-door, a bolt, D, located in the body of the car and adapted to be thrown out and locked against the end of the door, a graduated drum, G, and mechanism connecting the bolt and drum, whereby the movement of the bolt for locking against the door moves the drum,substantially as and for the purpose herein specified.

2. The combination, With a sliding ear-door, B, having hasp K, of the bolt D, having slot r, the saidhasp and bolt having corresponding seal-openings, yi t, and means for locking said bolt outward, substantially as described.

8. |The combination of a car-door, B, a lockingbolt, D, located in the car-body and adapted to be thrown out and locked against the end of the door, bolt-locking'lever E, graduated druin G, provided with ratchet-teeth H, paWl z, and key F, substantially as and for the purpose herein specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
